Jessa Duggar's recent online activity hints she might be pregnant with her first child. The "19 Kids and Counting" star got married to Ben Seewald on 1 November.

Speculations are rife that Jessa Duggar of "19 Kids and Counting" fame and husband Ben Seewald are already expecting their first child.

While the couple who got married on 1 November is yet to make an official announcement, media outlets have been wondering if another grandchild is on the way, after Jessa altered an Instagram post on motherhood.

On Christmas Day, Jessa posted a touching message to her pregnant sister Jill calling her an amazing example of what it means to be a wife, and according to a report from the Ashley's Reality Roundup, Jessa's initial post spoke about motherhood as well.

"So thankful for this sweet girl Jill, you're such an amazing example to me of what it means to be a loving wife—and now a mother also! I love you so much!! So blessed to call you my sister," a screenshot of her original post, which was immediately deleted, read.

Online users were quick to question Jessa if she was pregnant, but the reality show star ignored pregnancy-related queries, and quickly modified the post to read, " So thankful for this sweet girl! Jill, you're such an amazing example to me of what it means to be a loving wife! I love you so much!! So blessed to call you my sister."

Aiding pregnancy rumours is the fact that the newlywed has only been photographed from the waist up in recent times, according to Radar Online. Analysing her social networking accounts, the media outlet also noted that Jessa might be dealing with pregnancy cravings as she has been posting about food on Instagram.

However, there is a possibility that these pregnancy talks might be just rumours, as even if she was pregnant Jessa wouldn't be far along for a baby bump to be visible. As for the Instagram post on motherhood, chances are Jessa was talking about Jill's impending motherhood.

As for her future plans, Jessa previously told People magazine that she wanted a big family, and wouldn't mind adopting. "We both want to have a big family," she said in April. "We are talking about our goals and the future with family. We have both talked about adoption and want to adopt, too."
